LDO Electrical Characteristics

(1) (2)

Unless otherwise noted, VIN = 5.0V where: VIN=VVIN = VVIN_LDO. C1 = 4.7µF,C6 = 2.2µF.

The application circuit used is the one shown in "Typical Application Circuit."

Limits in standard typeface are for TJ = 25°C.

Limits appearing in boldface type apply over the entire operating junction temperature range of

−30°C ≤ TA = TJ ≤ +85°C.

(1)

All limits are ensured by design, test and/or statistical analysis. All electrical characteristics having room-temperature limits are tested

during production with TJ = 25°C. All hot and cold limits are ensured by correlating the electrical characteristics to process and

temperature variations and applying statistical process control.

(2)

Capacitors: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics.

(3)

Specification ensured by design. Not tested during production.

(4)

Dropout voltage is the difference between the input and output at which the output voltage drops to 100mV below its nominal value.
